Question

22. A dealer marks his book 40% above the cost price and gives a discount of 35% on market price find the profit or loss %.​

Answer 1

Step-by-step explanation:

mp = 1+40%cp=(1+0.4)cp=1.4cp

sp= mp(1-d)

sp = cp(1+g)

=> mp(1-d) = cp(1+g)

1.4 cp(1-d) = cp (1+g)

1.4(1-d)=(1+g), d=35%=0.35

1.4(1-0.35)=(1+g)

g+1=1.4× 0.65=0.91

g= -0.09

loss% = 0.09 x 100 =9%
